ABSTRACT: The weight certification program for wrestling requires a urine specific gravity (Usg) < 1.020. However, the effect of acute rehydration on percent body fat (%BF) and minimum wrestling weight (MWW) is largely unknown. We examined the effect of acute fluid consumption on %BF and MWW. Twenty-five male subjects (18-22 y) were tested in a [...]
Attention on beverage intake, specifically sugar-sweetened beverages (SSB), has increased in recent years. A brief valid, reliable and sensitive assessment tool for quantifying beverage consumption and determining its influence on weight status could help to advance research on this topic. The valid and reliable 15-item beverage questionnaire (BEVQ-15) estimates mean daily intake of water, SSB [...]

Short bowel syndrome (SBS) is characterized by nutrient malabsorption and occurs following surgical resection, congenital defect, or disease of the bowel. The severity of SBS depends on the length and anatomy of the bowel resected and the health of the remaining tissue. During the 2 years following resection, the remnant bowel undergoes an adaptation [...]
There is a lack of studies concerning hydration status of young athletes exercising in the heat. PURPOSE: To assess pre-exercise hydration status in young soccer players during a summer sports camp and to evaluate body water balance after soccer training sessions. METHODS: Initial hydration status was assessed in 107 young male soccer players (age: 11-16 [...]
Good fluid intake in children is vitally important as they have immature thirst mechanisms, relatively high rates of fluid loss and are physically active. Poor fluid intake may affect children's cognitive functioning as well as bladder control. Research shows that children drink seven times as much soft drink as water. Schools have a vital role [...]
Both acute and chronic fluid deficits have been shown to be associated with a number of adverse health outcomes. At the extreme, deprivation of water for more than a few days inevitably leads to death, but even modest fluid deficits may precipitate adverse events, especially in young children, in the frail elderly and in those [...]
The field of research examining the link between dehydration and endurance performance is at the dawn of a new era. This article reviews the latest findings describing the relationship between exercise-induced dehydration and endurance performance and provides the knowledge necessary for competitive, endurance-trained athletes to develop a winning hydration strategy. Acute, pre-exercise body weight loss [...]
Loss of body water, if sufficiently severe, impairs most physiological functions, but the body water content fluctuates over the course of a normal day with no implications for physical or mental performance. The point at which an effect of dehydration becomes apparent has been the subject of much debate, in part, at least, because of [...]
OBJECTIVES: To assess effects of dehydration on tooth colour. To investigate any change in tooth colour resulting from dehydration and the time required for any change to return to baseline. METHODS: 20 subjects with intact maxillary central incisors were recruited. In each case one incisor was randomly assigned as test tooth with the other acting [...]
